A national union says it was told by Stellantis this week that it is seriously considering the closure and sale of the Brampton Assembly Plant.

Unifor national president Lana Payne told reporters on Friday that the union “received information” from Stellantis on Wednesday about its possible plans, but Stellantis has not provided the union with formal written notice of closure of the plant as required under its collective agreement.

Payne said the company is required under the terms of the collective agreement to give at least one year’s notice to the union of any such closure or sale. She said the company has indicated its intent to open discussions with another company about the potential sale of the plant.

“To say that we are disappointed would be an understatement,” Payne said. “This is a gut punch to our union and to our members, most importantly to our members, the workers who have given everything to this plant.”

In a statement on Friday, Stellantis said: “We are preparing to enter the collective bargaining process and have nothing to announce at this time. Our focus remains on finding a sustainable manufacturing solution for Brampton Assembly.”

‘None of this is unacceptable,’ Unifor says

Payne said the plant had been slated to be retooled for Jeep Compass production, a process that began in January 2024 but was paused in February 2025.

In October 2025, the company informed the union that it was going to move Jeep Compass production slated for Brampton to the U.S., a move that would idle the plant indefinitely.

“There is absolutely no replacement for high paid union jobs developed under an auto sector collective agreement built up over 80 years,” Payne said.

She said the union will bring up the issue with Stellantis in upcoming contract negotiations.

“None of this is acceptable to our union and nor will it be acceptable to our members. The workers of Brampton and this country deserve so much better,” Payne said.

More to come.

The Windsor Assembly Plant will be down with workers off the job for two weeks starting Monday, Unifor Local 444 announced Wednesday evening.  

The plant will be down the weeks of April 7 and 14 — and in a social media post, the union warned more changes to the schedule are “expected in the coming weeks.”

“While we had heard rumours of potential downtime, the company said there are multiple factors at play, with the primary driver behind the final decision being this afternoon’s announcement from U.S. President Donald Trump of the U.S. tariffs,” the union said in Facebook post. 

“This has and continues to create uncertainty across the entire auto industry. This is not just affecting our plant—it’s impacting facilities in the U.S. and Mexico as well.”

A company representative could not immediately be reached for comment.

Earlier on Wednesday, Trump announced sweeping tariffs on a wide range of countries. And while Canada was spared from any new tariffs, automotive tariffs announced by the president last week come into force Thursday. 

Those 25 per cent tariffs are expected to apply on the value of the non-American content in the vehicles. But parts imported under the Canada-United States-Mexico Agreement (CUSMA) are expected to remain tariff-free, for now.
